I don't understand font embedding, what does it mean and why is it so important?

All fonts must be embedded in a PDF for us to print from the file. Embedding a font is the act of properly including fonts in a document so the typefaces can be rendered properly when printing.

Using embedded fonts guarantees that the reader of the PDF will see and reproduce the original font, regardless of whether or not the font is installed on their system. In instances where your fonts have not been embedded, the print system may try and substitute with close or available fonts.

Due to licensing and copyright restrictions, bookvault does not keep a font library, therefore, we are dependent upon our customers' PDF files to have the embedded font information to ensure proper printing representation of the book cover or interior.
